How to create a centered window

[BlackVortex]

I thought this would be trivial, but after a lot of searching around MSDN,google,this forum's search etc I utterly failed !

Here is the situation, I create a dialog with these resource properties :

Code Select Expand

whatever DIALOGEX 300,150,196,165
FONT 8,"Tahoma",400,0,0
STYLE WS_POPUP+WS_VISIBLE
BEGIN
END

And I use this command to create it :

Code Select Expand

invoke DialogBoxParam, hInstance, ADDR DlgName,NULL,addr DlgProc,NULL

How can I set it to be created centered to the desktop/screen or as a last resort what's the best way to center it to the screen on init ?

You must calculate the postion yourself when processing WM_INITDIALOG message.

1.Get the screen size using GetSystemMetrics
2.Get the size of your window
3.Calculate the center position
4.Set the window position using SetWindowPos
